Illustrates how heuristics can provide a psychological narrative of Hippocrates' and Archytas' thinking on the duplication of the cube. Four general heuristic techniques were used. (YP)

This article discusses problem solving and how science educators can integrate problem solving into their instruction. The Search, Solve, Create, and Share (SSCS) model was developed based on the findings of problem solving research. (YP)

Introduces a framework for comparing and evaluating knowledge representation schemes based on the requirements for "good" representation discussed in extant literature. Comparative analysis and evaluation of four popular knowledge representation schemes--Logic, Production Rules, Semantic Nets and Frames--are discussed in support of validity and…

A conceptual framework of cognitive growth is sketched and a mathematical model of cognitive growth is presented with the conclusion that the most plausible model is a model of logistic growth with delayed feedback. The model is transformed into a dynamic systems model based on the logistic-growth equation. (SLD)

In a comparable case-study approach, 174 adults answered open-ended questions identifying that (1) degree of self-directed learning was not age related; (2) some emphasized mutual responsibility for learning; (3) learning experiences were largely problem centered; and (4) experience was integral to their learning. (SK)

The explicit, experimental introduction of a series of logical inconsistencies is described and recommended as a means of disrupting the faulty logic and, thereby, enhancing the use of more appropriate probabilistic reasoning by graduate students enrolled in an introductory inferential statistics course.

Two methods are proposed for the construction of weakly parallel tests based on a prespecified information function. A method is then described for selecting weakly parallel tests that are optimal with respect to the Maximin criterion. Numerical examples demonstrate the practicality of the tests. (SLD)

In this study, 36 Serbian/English bilinguals and 42 English monolinguals (aged 5-8 years) received a successive name training assessment of 2heuristics: criterial use of highlighted features and preservation of mutual exclusivity. Results support the view that monolingual and bilingual acquisition fosters the development of different word learning…

Offers heuristic arguments showing that a simple closed curve of specified length that encloses a maximum area must be a circle. Develops the problem by demonstrating that such an n-gon must be convex, that such a convex n-gon must be regular, and that such a simple closed curve must be a circle. (MDH)

Maintains that criteria development--the process of creating standards against which to measure options--is not an objective process, but a subjective one in which criteria need to be revised in light of available options. Revises E. Banset and G. Parsons' problem-solving heuristic to more accurately reflect this subjectivity. (SR)

A model for solving very large item selection problems is presented. The model builds on binary programming applied to test construction. A heuristic for selecting items that satisfy the constraints in the model is also presented, and various problems are solved using the model and heuristic. (SLD)

Five experiments involving a total of 268 college students indicate that people are especially likely to overinfer quantity or probability from numerosity when they are asked to make inherently difficult judgments, when they are asked to render judgments while performing a concurrent task, and when they are forced to make rapid judgments. (SLD)

Explores the problem-solving behavior of a university lecturer as well as that of undergraduate and graduate students. Identifies and describes 14 physical and cognitive actions employed in the problem solving. Contains 28 references. (DDR)

Examined the effectiveness of the Pedagogical Heuristic Device (PHD) in encouraging preservice teachers to use a wide variety of cognitive processes and critically apply what they learned in courses on decision making in the classroom. Results support the use of the PHD to help preservice teachers learn to reason about pedagogy. (SM)

Examines the role of prototype case studies as the foundation for later evaluation through two studies from the "R&D Value Mapping Project," a study that will involve more than 30 cases. Explores the usefulness of case studies in defining and assessing subsequent research efforts. (SLD)
